Summary

This study tests a combination of two targeted drugs (ruxolitinib and venetoclax) plus standard chemotherapy in children and young adults up to age 21 whose leukemia or lymphoma has returned or not responded to treatment. The goal is to find the safest dose and see how many patients achieve remission. Only 26 participants will be enrolled in this early-phase trial.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: ruxolitinib, venetoclax, dexamethasone, cyclophosphamide, cytarabine, and intrathecal chemotherapy
What this could lead to: If successful, this could offer a new treatment option for children with hard-to-treat blood cancers that have come back or not responded to standard therapy.
What could go wrong: This is an early-phase trial with only 26 participants, so results may not apply to all patients. The drug combination can cause serious side effects, and it's not yet known if it will work better than existing treatments.
